Coils for concentrate dryers.

Five new super duplex coil sections for dryer 6 of the Chuquicamata smelter, fabricated between China and the Calama shop, with their installation on site.

Processes and equipment

The concentrate enters the dryer wet. The coils remove its moisture before smelting. Five new super duplex sections for the Chuquicamata dryer 6.

Lifting a coil section

The dryer is a rotating drum with heated tube bundles inside, the coils, which remove moisture from the concentrate before smelting.

For dryer 6 of the Chuquicamata smelter, LTF fabricated five new coil sections in super duplex steel, between China and its Calama shop, including the welding, bending and drilling of the matrices. On site it removed the existing sections, installed the new ones, repaired the dryer shell with plates and welding, and replaced the piping and electrically actuated valves. The job was carried out in 2024 with 140 people on rotating shifts.
